Abstract : This users manual describes PRECISE - a completely assembled interpretive program for the IBM 7090/7094 which enables the user to carry out arithmetic operations and function generation in multiple precision (accuracy to 28 significant figures). PRECISE operates as a sub-monitor under the IBSYS or DC-IBSYS monitor systems. Appendixes describe how jobs are set up to be run under the PRECISE sub-monitor, and how the system may be expanded to include new subroutines. The program, which responds to instructions in the form of plain English sentences or contractions thereof, has provision for handling numbers out of the normal 7090/7094 range. It handles numbers as large as 10 to the 10 to the 9 power. Other features of the program include: free-field input; a work-sheet of 7,500 cells ((3x2500 computer words) which can be dimensioned by the user at run time (75 rows by 100 columns, 300 rows by 25 columns, (etc.); solution of systems of linear equations in as many as 85 unknowns; flexible formatting; tape handling facility; and row and column sums.
